METHOD FOR FASTENING PYROTECHNIC ELEMENTS OR FIRECRACKERS TOGETHER FiledApril 3, 1929 I gwuemtoz Thamas 5. Hi2? Patented Apr. 15, 193% PATENTQFFICE THOMAS G. HITT, OF SEATTLE, WASHINGTON METHOD FOR FASTENINGPYROTECHNIC ELEMENTS OR FIRECRACKERS TOGETHER Application filed April 3,

' This invention relates to improvements in packages and methods fordetachably fastening a plurality of pyrotechnic display members orfirecrackers together.

An object of this invention is to provide a means or method by which aplurality of firecrackers or other suitable elements may be detachablylinked together, thereby providing a grouping of elements acceptable andconvenient for marketing.

A further object of this invention is to provide a bundle or pluralityof firecrackers detachably linked together by means of their fuses, insuch a manner that each element or firecracker may be separated from thebundle without severing, cutting or breaking the fuses.

Other objects of this invention will appear from the following detaileddescription and 2 as disclosed in the single sheet of drawings which isherewith made a part of this application.

In the drawings- Figure 1 illustrates a perspective view of a bundle orplurality of firecrackers linked to gether, and disclosing onefirecracker or element separated from the bundle.

Figure 2 illustrates a vertical sectional view of a plurality offirecrackers, and the means by which they are detachably connectedtogether, one of the firecrackers being in section for disclosing theexplosive substance and chambers therein.

Figure 3 represents the top plan view of Figure 2 disclosing the fusesinterlinked to gether. 7

As one modification of this invention it is preferred that numeral 1designate a plurality of firecrackers detachably linked. or connectedtogether by means of fuses 2, which are made in loop formation, the freeends of the fuses 8 being adapted to extend a suitable distance withinthe firecracker 1 as clearly disclosed in Figure 2 of the drawings.wherein numeral 1 designates a seal through which the fuse 2 extendsinto the firecracker, the loose ends of the fuses 2 being preferablytwisted as disclosed in Figure 2 in order to form a'more efficientanchoring within the firecracker 1, the inner ends 3 of the fuses 21929. Serial No. 352,237.

are adapted to contact with an explosive substance consisting of somesuitable explosive such as white powder 5 and brown powder 6.

In order to detachably fasten the plurality of firecrackers or otherelements 1 together it is preferred in this invention to assemble eachfirecracker as clearly disclosed in Figure 1, extending the loop tofuses 2 in series one through the other, in such a manner that thebundle or group of the firecrackers may be easily disassembled byremoving the loops one from the other as disclosed in Figure 1, and atthe same time making it possible where desired to ignite the fuse at oneend of the assembled group, which would automatically function to ignitethe fuses in each of the ex plosive elements thereby producing apyrotechnic or explosive display of a plurality of firecrackers.

This invention provides very efiicient means or method for grouping aplurality of firecrackers or other suitable elements into a bundle, andin such a manner that each element may be separated from the bundlewithout the cutting or the damaging of any por tion of the connectingmeans, which in the preferred instance is the looped fuse of eachexplosive element.

A bundle of firecracker elements may be assembled according tothisinvention of any desirable size and is extremely convenient for shippingfor either wholesale or retail purposes.

The bundles of pyrotechnic display or firecrackers may be readilyseparated into their single units for exploding purposes or retained inany plurality of groupings for the purpose of plural explosions.

As actually assembled, the fuse of the firecracker to be attached isinserted through the adjacent firecracker-fuse loop. To do this it isnecessary that the firecracker be turned until the fiat portion of thefuse loop will fit into the length of the fuse loop of the adjacentfirecracker, after which the firecracker to be attached will be turnedapproximately forty-five degrees so that the length of the fuse loopwill be in line with the adjacent loop, thus securely locking'the sameto the adjacent firecracker. The usual procedure is to bend the fuseloops over and flatten the same before interlocking; but the bendingover step may be done, With the exception of the first firecracker onthe string, after the fuse loop has been inserted through the adjacenttuse loop. The step of adding subsequent firecrackers is repeateduntil the desired nmnber have been secured together.

This presents a very unique and superior means of the stringing andassembling of crackers together, and at the same time, a

very attractive package is presented.

Having described my invention, What I claim as new and novel is:

l. A method for detachably connecting togetl er aplurality ofpyrotechnic display elements having looped fuses, consisting ofconnecting each pyrotechnic element together in series by linking theloops together.

2; A method for detachably connecting together a plurality ofpyrotechnic display eleinents having: looped fuses, consisting ofconnecting each pyrotechnic element by linking the loops together.

A- method for detacliably connecting a plurality of pyrotechnic displayelements having looped fuses, consisting in connecting the elementstogether in series by passing the loops or" each through the loop of theelement preceding it in the series and bending each interlock-ed loopsubstantially at right angles-to the aXis of each element.

l. A method for detachably connecting a plurality of pyrotechnic displayelements having looped fuses, consisting of turning the element to be.attached to another element at substantially right angles to that otherelement, then inserting the loop-of the i :t named element through theloop of the 89nd cther element and turning the attached element untilits loop issubstantiallyin line wi :hato't the other element.

A package for pyrotechnic display elemr ts comprising.firecrackers.having looped fuses, each of said firecrackers connected to the adjacentfirecracker by means. of said P- i A package of-pyroteclmic' displayelements comprising firecrackersihaving;looped fuses, each; ofsaidlooped fuses bent; at suhstantially a right i angle to the axis ofthjefire cracker containing said loop, each of said firecrackersconnected to the adjacent firecracker hy the interlocking of theirloops.

7. A package of pyrotechnic display elements comprising firecrackershaving looped fuses, said looped fuses bent at substantially a rightangle to the axis of each element, said loops flattened'toreceive theloop of the adjacent firecracker.

8. A package of pyrotechnic display elements comprising firecrackershaving looped fuses, each of said'tirecrackers connected to th adjacentfirecracker by means of said loop, the length of the loop being greaterthanthe width-thereof.

In testimony whereof I atfix my signature.
